![]() ![]() The aim was to compare the non-invasive vascular unloading to a semi-invasive pulse contour analysis reference technique for continuous CI measurements in bariatric surgical patients. Evidence on the clinical reliability of alternative semi- or non-invasive cardiac monitoring devices is limited. While invasive catheterization may bear technical difficulties, transesophageal echocardiography is contraindicated due to the surgical procedure. Thus, an advanced hemodynamic monitoring including continuous cardiac index (CI) assessment is desirable. In morbidly obese patients undergoing laparoscopic bariatric surgery, the combination of obesity-related comorbidities, pneumoperitoneum and extreme posture changes constitutes a high risk of perioperative hemodynamic complications.
